Hi everyone, my HD2 just stopped working with no signal at all.and shows a exclamation all the time, sim cards are no problem. i've updated the phone with official sw, still have this problem at the beginning.
has the phone been blacklisted?
is the phone turned on in wireless mode in settings? ( ya never no)
is it still under warranty?
My HD2 has done the exact same thing, just shows an !
it doesnt even try to find a signal.
phone was a tmobile UK version, which was unlocked to use any network.
the problem has literly just happened today.
have tried different offical roms, and different sim cards.

Just phoned my provider in regards to my phone, quoted the emei and have been told the phone is blacklisted.
they are sending a request to have it unbarred. will post the outcome.
I have had this happen alot with Vodaphone UK. This is a brand new number so doubt it has been black listed.
I can get this working my turning the phone to airplane mode then back to phone mode, this most of the time makes the phone look for a signal.
Usually happens to me when there is no signal like in a tunnel, the phone does not seem to try looking for the network until you force it to.
This is possibly a fault with the timeout of the HTC HD2. Could be once it tries to connect when out of signal the device gives up after a number of attemtps.
Does anyone know?t

I was searching before posting for just this problem.
It is really irritating me. The phone can jump from deciding there is no signal to sometimes even going to full-bar "H"!
I hav currently resorted to turning off 3G as at least that way I am eliminating the idiocy of it prefering 0/1 bar of "H" vs near full non-3G reception for calls.
Even so at times it will just sit there for ages having dropped a signal with the exclamation showing and then jump back to life [in the same place] with good reception.
I am also on Voda UK
Mine has done that twice, in 4 months. 1 time phone was turned off inside connections, no idea how? 2nd time I just shut off, & back on, signal was back, hasn't happened in months now?
so does anyone have a solution to this problem?
I've checked with my service provider and my phone is not blacklisted...
My SIM card seems fine and everything else seems fine, except it keeps giving me the exclamation mark.. most of the time i notice it's when i get out of the lift (but that could be because that's when i usually check my phone before I put it on my desk).
There are many occasions (probably 5+ times/day) where I turn my phone on (ie, off standby) after it's been sitting on my desk for an hour or so to check calls, etc and there is that dreaded exclamation mark.
I know the area around my desk does have a signal because the guy next to me on the same network has a strong 3G and 2G signal.
Sometimes going to Comms to turn airplane mode on and off to force it to look for a signal works, but sometimes it doesnt.
I've tried soft-resetting, hard-resetting, using different radios, different ROMs, etc and still no good.
Funny thing is, it's only been happening over the past 2-3 weeks.. and I'm not sure what triggered it.
It's really starting to frustrate the crap outta me and friends have been asking why they can't get through...
Any help would be appreciated.. . I'm trying to avoid sending it to the HTC service centre if I can because they're slooooow and the stories I've read about my local centre are pretty bad (when I had my HTC diamond).
Solved:upgrade your rom everything gonna b in place
Upgrade to what?
I am having the same problem, for a hile now. Been fiddling with phone settings parameters, trying to see the effect. One particular combination so far seems to work. Try this: Comm manager --> Phone --> Tap Change Phone settings --> Menu --> Advanced network --> GPRS --> select CHAP authentication --> then CSD Line Type --> select Data rate 9600(v.110). Then OK, Back, and Done with the Comm manager. Observe if the network pickup performance (switching from non-existent H or 3G to E or G) works better for you after that. It does better for me, so far.
I'm having the same problem - NO SIGNAL
Any solution?
i recently discovered that for my problem, it was to do with the earphones. Not sure why, but it only seems to happen to me not long after i plug or unplug the earphones.
I usually have my HD2 on my desk with the music going while I work, but every hour or so, I unplug the earphones and take my phone by itself out with me for a cigarette.. then I come back and plug the earphones back in.
Often when I'm about to head downstairs, I turn on the screen while the music is still going and i see the "!"... as soon as I unplug the earphones, the bars indicating reception comes back straightaway!
Not sure if it's a coincidence or whether it really does have something to do with the earphone/earphone jack.
Since I upgraded to the Vodafone rom on the htc website I have not had this problem

I have just bitten the bullet and accepted the phone is crap at swithing between 2G and 3G signal so turn off 3G in a couple of locations when I know I get this problem [home - I can use WIFI] and my office.
HTC would not be drawn at all on un updated Radio and this problem being "fixed" in USA ROMs
Fixed
the very easy fix is to do this :
settings _ personal _ phone _ network then make network selection to manual ,, then choose ur provider,,, then u will have signal,, after that u can turn it back to automatic
100% working
Thanks a "fix" not a solution.
Rather silly to have to jump through hoops to make a mobile phone recognise available reception
Have the same problem
I have the same problem now, any solution for that?
I have my sgs for 2 weeks now. GSM disconnects around every 2 days.
At service mode (*#*#4636#*#* - Phone information) i can see this repport:
GSM disconnects:
====DATA=====
State: inactive
disconnected with last try
at 00:59
fail because No Error
The question is: why does this happen?
Is this an android issue or a hardware problem?
Any pointers?
Thanks in advance
.
do you ever enter a building, subway, or some other location where the GSM becomes poor?

That's not the problem.
Gsm disconnects just like that ,at home for instance. And when I notice that and try to reconnect (settings- wireless networks- mobile networks - networks operators) it doesnt find ANY of them.
Then I restart the phone and gsm network is back.
If I dont notice disconnection in time (so I can restart phone, people just cannot reach me....quite frustrating...
i see what you mean now.
yes, i've noticed that on mine too, but.... that's because i was fooling around with some new Apps Widgets settings i was testing to control the radio and data to save battery.
Did you install any new Apps recently that might cause that?

do you have an old sim card? i had a 3g sim card that wasnt even 1 years old and replacing it fixed connectivity issues on my nexus 1 and i had a similar experience with my old htc magic

Well I installed all kind of apps. but i have the feeling this problem was happening even before that.
And I dont need widgets to control data ( I think) because I set the sgs to use 2g networks only and I dont have apn configured( section is empty. Internet connec. only via wifi.

Well, my sim card is VERY old (2002) and the carrier (Telfort) is roaming into another carrier's network (Kpn) with no extra costs of course like real roaming, but still roaming (I get the little "R" next to the signal strenght bars)
Anyway this never happened with the Nokia 5800xm running Symbian OS and using the same sim card...
Starting to get pissed of with Android...
With Symbian you hack or root or tweak because you want to, not because you NEED to like with Android....
And then you prob. get side effects...
Thank you guys for your time
I would get a new sim card if I were you. Every android phone that I have had seems to work better with a good 3g sim.
Get a new SIM card.
same problem, different phone
i have the same problem on kaiser with flashed android on it.
sim is 2 years old, and now suddenly this happened, tried differents sim cards, but the problem persists. My guess is, it is a software problem.
Maybe i will report when I flash original WM6.1 rom onto it, if you are interested in the result
btw, this happened about two days ago and because of this im buying galaxy s so i hope the problem will be gone with new phone
did you guys see this other topic?

Why you think the problem will be gone if it's still android and I also got it with my sgs? Or are you counting on Froyo?
Yesterday I upgraded my sgs to froyo jpc with kies. I am new with Android but the post of Aery was so clear that i didnt resist: http://forum.xda-developers.com/showthread.php?t=769400&highlight=froyo+upgrade
I did get stuck on reboot but could get out of it after applying a cache/data/factory reset on recovery mode (3 buttons)
Now I am being carefull with the 3rd party apps., and so far so good, no gsm disconnections .
Froyo is of course better that eclair but Android is still disappointing to me.
You flashed Android onto a WM device (i'm impressed); could you not teach me how to flash Symbian onto my SGS?
Voice dialing (over bluetooth or not) and proper connectivity control (network, data, gps and bluetooth) of android is years behind Symbian; and such a well written, light OS, it will just fly on a high-end hardware like the sgs; but that is an issue for another thread.http://forum.xda-developers.com/showthread.php?p=7938430#post7938430
Pls keep reporting..

I think indeed that's not the same issue. My problem is that the radio signal get turned off during inactivity. That's why I got connection back after reboot: radio signal gets turned on again; later I learned how to turn radio signal back on without rebooting, but that is just a remedy , no real solution.
Try to upgrade to froyo, make a factory reset and be carefull with 3rd party apps. With froyo you will need less interfering tools anyway
I dont thing that my old sim card is the problem, but i'll try to replace it anyway...but first things first
Btw dou you have 3g turned on? Cause I never...
Another mistery: When I have 3G on I see those bars (signal strenght) dancing and that "death grip" thing happening:http://www.youtube.com/watch?v=LROTHrTR92k
But when I have it on 2G only the bars doesnt move even if I strangle it with both hands.....
Please repport later how it's going...
I had the same issue, i sent mine back and got my money back, i had also tried with different simcards and resets and nothing worked.. so hopefully my new galaxy wont have this problem. Its strange that these problems are so rare though.. But as long i get it going ill be a happy man.
fourth day with JPC ( and 4 days after a factory reset) so far so good no disconnections . I think problem is gone...
Today just to be safe, I got a new sim card....the other one was too old anyway(8 years)
i have the same issue, for a few days i can't get 3g. i'm seriously wondering about sending back my sgs. i've ttried all the settings, changed my sim..nothing...begin to think it was a fullish thing to change Desire to SGS..

Well... this is not the same issue.
I have 3G (WCDMA) disabled. I only use 2G (GSM) and WIFI for data/internet connection.
I Dont have a data account, I dont need it therefore I disabled 3G in order to save battery.
If you do want to use 3G, just go to settings - wireless and network - mobile network settings - network mode and set auto-mode (GSM/WCDMA or 3G/2G)
If it doesn't work, apply a data/factory reset and try again.
And if it doesnt work, it's probably hardware related and you should return it or send it for repair.
My issue is more complicated; next to the fact that I dont want to use 3g, my carrier is roaming to another network and probably Android OS or the firmware cannot handle it properly.
Android is still premature and the "Samsung - Android integration" seems to need a lot of development as well.
It is just a shame that basic functions like proper connectivity control just wont cut it. And Google is not doing any good either.
And dont let me get started on the voice recognition issue......
Hardwarewise, the SGS is superior that htc desire.....I wonder how it would perform if running Symbian^3 OS or Meego.....
I get a great sound quality from the stock music player just by mixing the equalizer and using the music clarity effect...just great...better than any other device I tried.
And the OFFLINE Gps experience is just great as well: the combination SGS - Motonav - External Bluetooth gps device is working like a charm.
I wouldn't change my sgs just yet......
yesterday i was swiching sims to determine if is a sim fault and suddenly i have my 3g/h back. happy owner again. i've tried all to do this, from firmware upgrade to servide mode settings..i don't know why but i'm ok again...

Hello,
I know its been a long time since you wrote this thread but I just came by it!
I have the exact same problem with you (I had it since August) even now with the official froyo. I tried factory reset and no new apps (that could cause the problem) but it still disconnects randomly in GSM mode. However, when I have it on auto (gsm and wcdma) I have no issues. I just disconnect data from the power button in froyo. I am wondering if you ever found a solution..
Chryssa
Well, I am subscribed to this topic so I saw your post.
Good and bad news:
First the bad one: No solution yet, it keeps disconnecting IF I stay on "gsm only".
And the good (or a little better) news:
I noticed that on sgs, using "gsm only" or "gsm/wcdma (auto mode) makes no difference on battery consumption....
By the way, this is a Samsung issue, not really an Android one.
On a HTC Desire HD, you can use "gsm only" mode with no problems...
Thank you for your answer!
I noticed that about the battery too. So not too bad, I just have to keep it on auto mode then..
Same issue
Im having the same issue but in a optimus t the worst part is that i cant get service at all.. when i press change network preferred it wont change and when i try to press on turn on radio it wont work either....
Hi,
I have a weird problem with my S4.
At work I have some areas with really bad coverage so sometimes the phone can stay for a few minutes (or even say 1h) out of service.
This is all normal. The coverage sucks, the building is weird, not problem here.
The problem is that when I go outside where the signal is normally full it does not register back to the network.
Even more it does not even go to "emergency only mode". On a few occasions I arrived back home (10Km + drive) until I realized people can't call me because the phone is out of service.
What is even weirder is the fact that on some occasions, even though the (no service) (/) sign is displayed mobile data works just fine.
My previous iPhone did something similar too - it took a while for it to recover signal after exiting the coverage black spots but never more than maximum 5 minutes.
To me it looks like a radio modem issue and maybe this is aggravated by the fact that my carrier uses the same 2100MHz frequency for both Data and Voice.
I would like to know if any of you have experience anything like this or if there is some app available that can monitor what's happening.
what network and firmware you on and wich s4 variant:thumbup:
Sent from my GT-I9505 using xda premium
I9505XXUBMEA I9505OXXBMF1
It's Europe standard i9505.
Network is Digi.Mobil Romania - but I doubt it's relevant since it can't get even emergency only (other networks).
so... any idea?
Android needs to work on it's notification. No Service and the reception bars only gauge voice coverage. You can test this out by using Service Mode to do a PS Only (data) attach instead of the standard PS + CS (voice) attach. It'll say no service, but data will be fine.
Emergency only, is when there is coverage from other operators but not yours. No service, means your way off the grid.
I've noticed the issue you describe and it's only on some firmwares. Try a newer one and see if you still have the same issue. But you might notice a drop in your battery life because your phone will be scanning all the time. If you're happy with no coverage at work, best to just turn it off and then turn it on when your outside.
Best option is to tell your operator about the lack of coverage. There's someone in charge of stats who get's beaten every time you drop a call. You'll get extra attention if you've got other businesses around you, so let them know that too.
Thanks for the reply.
I am already on the latest firmware and I noticed the same behavior on the firmware before this one.
Unfortunately I can't try out other modem versions (from other FW packages) as that would void my warranty.

but...what about reboot phone? i know isnt funny but until u find a problem u can just reboot ur phone while u are going out from ur office...or just try to enable and disable airplane mode
Of course reboot works but I am looking for a solution, not a partial workaround.
The most annoying problem is that if I forget to reboot it when I leave work it will not recover network connectivity even if I am in areas with very good coverage, areas where you would expect your phone to work.
It looks like when it decides to give up it does not try again. It is very weird that it also drops the signal from other networks (the "emergency only") even if it's well in their coverage areas. I guess I will have to switch phones... Even if this issue was present for the iPhone too it never took more than a few minutes for it to recover on its own. And I'm not an apple fan
Just to do some brain ecercise...do u keep in power save when u are out of signal ? Its possible that disable check after few tries
Sent from my GT-I9505 using xda app-developers app
It's not in power save. I only use that function in case of battery emergency.
Same problem here
Hello, I have the EXACT same problem here. I am in Argentina.
Now, I've been in the USA for a few weeks, visiting, and while my phone was roaming, I didn't have a single problem with my phone.
Since I came back, 3 days ago, I haven't had any problems in Argentina, either.
Is it possible that something got activated when the phone was registered to another company? (it was AT&T i believe)
If that's the case... maybe you can try putting a sim card of another company and see if you still have the problem?
Please let me know if you still have the same problem or if you got it solved. I would love to know something more scientific about all this.
I don't know if this is relevant, but my compass is off by about 30 degrees. Maybe my phone is defective?
THANKS FOR ALL YOUR HELP YOU CAN GIVE ME WITH THIS

Hi I have similar issue,
My phone says its out of service or no signal or no network also I checked my sim card in other phone in the same place and it is fine. The i9505 model in ireland meteor provider was running ok until deicided to give a try to another network operator, when I changed the sim card it didnt only catch up the signal from new network provider but also it refuses to catch the old network provider. Funny thing is that I am receiving 3G but no signal bars and no service sign is beeing displayed. I am running latest official BTU (UK) firmware, the phone was never rooted, altough I had to remove the simlock and instal unbranded firmware. The phone worked fine with the newest updates for a month and now I am facing this trouble.
No factory resets nor installing same radio (couple of times) have helped. Also I used odin to instal same firmware (as it has locked bootloader) so I cannot revert back to other stock firmwares, but still no joy.
hope that someone faced the same problems and describe how to solve this issue. thanks
Hi guys,
I have a Samsung galaxy s4 lte 9505, phone is been working perfectly till last few weeks Im getting this annoying error:
SIM card removed The mobile network will be unavailable until you restart with a valid SIM card inserted
Ive tried to find a solution but is pretty confusing out there, some people says is hardware issue and others says is software. I did change my sim already and did an hard reset twice...Any help or tips would be so much appreciated
Cheers

Mate ,
Did you try the classics??
Clean sim contacts with an eraser
clean the phone sim contacts
make it tighter with a piece of paper or a plastic tape
Use your sim card in other phone ..or your phone with other sim card.....
sure I did, its a bug anyway It seems that if the network is unavailable, and the GPS is active, this error is triggered. It is especially bad with weather or other applications which are constantly accessing the GPS device and have a bigger chance of getting the messages.

For sure annoying ,
Looks like a hardware problem but is hard to tell at this point.
The problems started after any software upgrade or app installation?
Are you in stock or custom rom?
Do a hardware reset try it with out restoring your backup , see how it behaves
Under settings mobile networks try setting different networks modes and see if it helps
if any of above helps....maybe is software related , upgrade or flash rom again
Also you could try to really clean the sim try with a electronic contac cleaner , take battery out , spray ( watch out with the display), let dry and test again.....
I doubt its hardware is just a bug mostly on 4.4.2, Never had a prob before...I tried all...Since I have changed LTE thou error didn't come back...Im on 3g thou
I am still getting this error now and then!! ANNOYING arghhhhhh i need to fix this
Any help would be so much appreciated

Hello there, as topic says, my one plus 5 lost sim card and wifi connectivity.
OS:
Android version 9
OxygenOS version 9.0.3
I have tried:
Unplug / plug phone and sim etc multiple times ( both simcard slots)
Soft / Hard reset
Bluetooth seems to be working, not sure tho
Reseting all network setups thingy
Dialing *#06 doenst show me any MEID/IMEI code
Sim card is ok, working on my Iphone 4
Found couple threads about some modem firmware thingy, idk.
I havent dropped phone to water or anything, just normal outside humidity if something.
Everything else working normaly exept random lags while trying to figure wlan working. I still have warranty on so I guess ill send phone back there before trying any rooting this? Imo this seems like software issue.
Or any advice what I should try?
